If oyu haven't purchased a second router yet don't. Get a switch and a WAP instead of a router. the linksys WAP54G will default to 192.168.1.245 with no WEP, you can set up security on the access point and be done. If you have a second router already you can turn off DHCP on the wireless router and attach it to the wired router using one of the switch ports, not the WAN link. that will allow you to use the wireless feature without getting a second nat'd network into the picture.
